By Nora Denise Fortes de Fortes and Jocélia Grazia

Abstract

Treze espécies são hoje incluídas no gênero: S. apicicornis, Stål, 1860; S. beckerae Thomas & Rolston, 1985; S. calligera Stål, 1860; S. concolor Ruckes, 1958; S. costalis Ruckes, 1958; S. delphis Thomas & Rolston, 1985; S. inspersipes Stål, 1860; S. lobata Thomas & Rolston, 1985; S. rotundicornis Becker, 1967 e S. ruckesi Thomas & Rolston, 1985. Cinco novas espécies são descritas: S. indistincta sp. nov (Irai, Rio Grande do Sul), S. bicolor sp. nov (Ponta Grossa, Paraná), S. maculata sp. nov (Itatiaia, Rio de Janeiro), S. máxima sp. nov (Imbituba, Santa Catarina) e S. robusta sp. nov (Itatiaia, Rio de Janeiro) do Brasil. A análise cladística foi realizada usando 40 caracteres e 21 táxons. O gênero Tibilis Stål, 1860; Neotibilis Grazia & Barcellos, 1994 e Similliserdia Fortes & Grazia, 1998 foram usados como grupo-externo. A monofilia de Serdia foi sustentada por 3 sinapomorfias: ápice do escutelo com margens enegrecidas, machos com a parede da taça genital espessada com processos em aba, fêmeas com o espessamento da íntima vaginal situado na metade posterior das gonapófises 9 e projetando-se ventralmente. O subgênero Brasiliicola Kirkaldy, 1909 é considerado sinônimo junior de Serdia. São fornecidas ilustrações, mapas de distribuição geográfica e chave para as espécies.<br>Thirteen species are presently included in the genus: S. apicicornis Stål, 1860; S. beckerae Thomas & Rolston, 1985; S. bihamulata, Thomas & Rolston, 1985; S. calligera Stål, 1860; S. concolor Ruckes, 1958; S. costalis Ruckes, 1958; S. delphis Thomas & Rolston, 1985; S. inspersipes Stål, 1860; S. limbatipennis Stål, 1860; S. lobata Thomas & Rolston, 1985; S. quadridens Thomas & Rolston, 1985; S. rotundicornis Becker, 1967, and S. ruckesi Thomas & Rolston, 1985. Five new species are described: S.indistincta sp. nov. (Iraí; Rio Grande do Sul), S. bicolor sp. nov. (Ponta Grossa; Paraná) S. maculata sp. nov. (Itatiaia; Rio de Janeiro) S. maxima sp. nov. (Imbituba; Santa Catarina) and S. robusta sp. nov. (Itatiaia; Rio de Janeiro) from Brazil. A cladistic analysis was performed using 40 characters and 21 taxa. The genera Tibilis Stål, 1860; Neotibilis Grazia & Barcellos, 1994 and Similliserdia Fortes & Grazia, 1998 were used as outgroups. The monophyly of Serdia is supported by three synapomorphies: scutellum apex with darkned margins; males with the inner wall of genital cup thicker and with brim-shaped processes; females with the thickennings of the vaginal intima arising at posterior half of gonapophyses 9, and projected ventrad. The subgenus Brasiliicola Kirkaldy, 1909 is considered junior synonym of Serdia. Illustrations, a map of geographical distribution and a key for the species are also provided
